Abstract
  Flaring of gas often having high heating value results in considerable economic and energy losses in addition to significant environmental impacts. Power generation through combined gas and steam turbine cycles may be considered as a suitable flare gas recovery process. Thermal sea-water desalination ...  Read More

http://dx.doi.org/10.22050/ijogst.2019.171324.1494

Abstract
  In the present study, the permeabilities of CO2 and CH4 in terms of ideal and actual CO2/CH4 selectivity were investigated through the synthesized membranes of poly (ether-block-amide) (Pebax 1657) accompanied with poly (ethylene glycol) (PEG 400) and NH2-MIL125 nanoparticles. NH2-MIL125 nanofillers ...  Read More

Volume 8, Issue 2 , Spring 2019, , Pages 1-14

http://dx.doi.org/10.22050/ijogst.2018.110934.1429

Abstract
  In this work, adsorbents, namely bentonite and sludge, modified by iron and copper were used to remove the H2S and mercaptan from Kermanshah refinery. The used adsorbents are inexpensive materials, which substantially decrease the operational costs. The structure of the adsorbents was analyzed using ...  Read More

Volume 8, Issue 1 , Winter 2019, , Pages 47-59

http://dx.doi.org/10.22050/ijogst.2017.108360.1424

Abstract
  A series of copper oxide (CuOx) catalysts supported by oxidized multi-walled carbon nanotubes (OMWNT’s) were prepared by the wet impregnation method for the low temperature (200 °C) selective catalytic reduction of nitrogen oxides (NOx) using NH3 as a reductant agent in the presence of excess ...  Read More

5. An Experimental and Theoretical Analysis of Foam Formation in the Sour Gas Sweetening Process

Mahmod Fatemi; Bahram Hashemi Shahraki

Volume 7, Issue 4 , Autumn 2018, , Pages 79-89

http://dx.doi.org/10.22050/ijogst.2018.111128.1430

Abstract
  Use of amine solutions for the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas is the most common method, and, in this process, operational problems because of foaming are reported. Foaming can lead to the entrainment of liquid into downstream process equipment ...  Read More
